The Chinese word "艾迪" is formed through phonetic transliteration, where two characters are selected solely for their sound to approximate a foreign name, typically "Eddie". The character "艾" (ài) corresponds to the "Ed" sound, while "迪" (dí) matches the "die" or "dee" syllable, creating a combined pronunciation that mimics the original. This method prioritizes auditory resemblance over the individual meanings of the characters, which are irrelevant in this context, reflecting a common practice in Chinese for adapting foreign names into the writing system.
